ea. We may takeany length along the vertical as a 6 to represent the load W.Draw be parallel to AB to meet ac. Complete the paral-lelogram adbc with ab as its diagonal. The force ab isthereby resolved into two forces, ac representing the pressure 106 MOLAK DYNAMICS. upon the plane, and ad… … Fig. 65. employed. Now it may be proved geometrically that thetriangles adh and BCA are similar; i.e. da: ah:: CB : BA. But da represents the force/necessary to produpe equilibrium,while a6 represents the load or resistance r; CB representsthe hight h, and BA the length I, of the inclined…
